Extend the transition gradually over 2m to bring VDC up a curb. For example: to bring VDC from a 7″ deep cut up a curb the cut at the start of the back of curb which is around 11″ (4″ for the curb height plus 7″ trench) and bring it up gradually until it reaches back to 7″ from the surface of the sidewalk. The slab saw is used to cut the majority on the sidewalk, curb and road. A concrete chainsaw or cut ‘n break saw is used to finish off this depth unless a large diameter cutting blade is installed on the slab saw. If VDC does a turn in the curb, the transition is much shorter because of the lateral flex of the conduit and extra room in the corner cut. TeraSpan preformed Curb Transition Clamp may be used for VDC1 and VDC4.
